Trans & Diff Capacities - 5kTQ & Golf

I'm Bentley-less here at work, and the owners manual only lists automatics.
Does anyone know how much oil the transmission in a '87 5kTQ holds? How about
the rear differential in the same car? I'm gonna buy some oil for her today,
but I dunno how much I need!!! TIA. Oh yeah, anyone know how much oil a five
speed in a '86 Golf holds? Again, TIA!
